In order to answer this question you would need to figure out where the second parquet-avro dependency comes from. You can check your job via `mvn dependency:tree` and then check whether you have another dependency which pulls in parquet-avro. Another source where the additional dependency could come from is the deployment. If you deploy your cluster on Yarn, then you can get the Hadoop dependencies on your classpath. This is another thing you might wanna check.
